Br. H. Woodward — British Carboniferous Cockroaches. 53 



the " Brooch " and the " Thick-coal " at Coseley, near Dudley, and 

 form a part of the valuable collection made by the late Mr. Henry 

 Johnson, F.G.S., Mining Engineer, of Dudley, now preserved in the 

 British Museum of Natural History, Cromwell Road, London. 



The remaining specimen (Plate II. Fig. 4a, h) was placed in my 

 hands some years since, by the kindness of Mr. James W. Kirkby, 

 who obtained it from the Upper Coal-measures, near Meithil, on the 

 Fifeshire coast.

With the exception of Blattina insigms of Goldenberg from the Coal 

 of Saarbriick, and Etoblattina Mazona, Scudder, from the Carboniferous 

 of Illinois (Woodcut Fig. 4), this is one of the most perfect Cockroaches 

 yet discovered in the Coal. The specimen is exposed in a small 

 oval clay-ironstone nodule, so fortunately split open, as to show an 

 equally well-preserved impression and counterpart of the fossil. The 

 pronotum or prothorax is rounded in front, being 13 millimetres 

 broad and 8 mm. long, and is divided into two parts by a straight 

 line, clearly visible both on the impression and counterpart; the 

 central part of the shield has a slightly raised pyriform area, pointed 

 in front and broadly truncated behind ; the surface is transversely 

 wrinkled and bears a pair of minute spots near the anterior point. 

 The hinder border of the shield is rounded and somewhat deeply 

 emarginated on the median line. 



The mesothorax is 8 mm. broad, but its length cannot be seen, 

 being covered by the wings. 



The paired wings measure 25 mm. in breadth and 28 mm. in 

 •length (they were probably about 3mm. longer, but their edges are
